GPS LOW NOISE AMPLIFIER GaAs MMIC
GENERAL DESCRIPTION
The NJG1144KA1 is a low noise amplifier GaAs MMIC
designed for GPS, GALILEO, and GLONASS. This amplifier
achieves high gain and a good balance between ultra-low noise
figure and excellent VSWR, while low current consumption and
high IP3, respectively.
The NJG1144KA1 operates from +1.5V to +3.6V supply
voltage range and current consumes is as low as 3.5mA.
An ultra-small and easy mounting package of FLP6-A1 is
adopted.
